Thanks, that's a lot better explanation why some "060" demos work
with Hatari 030 emulation, but not 060 emulation (when using TOS
v4 which Hatari patches to work on 060).

I.e. those demos actually not being 060 demos, but 060 + instruction
emulation demos?

(Which doesn't make much sense to me, why one would slow down his
demo by relying on instruction emulation, instead of building
the demo with real 060 support?)
